I had had fine results with it in the past for dobro-type resonator guitar bridge inserts, that is why I tried it on the Erhu.

I made the bridge the avarege size, because now I rather wanted to test material than mass. The bridge is not round, but oval in shape. When I finished, I glued the canvas to its bottom and found the tone to my liking. Not as dark as black wood, but mellower for sure. The A string got softer as well.

I think now that boxwood is a good material, if your Erhu is too harsh on the higher notes, or if a less dark colored lower register is needed. Since it is damn hard, bridges made of it will last a hundred times longer than black wood or white wood...

Cheers!

Your experiments look really interesting. If you have some extras lying around, could you mail them to me?

I think we are onto something that is really fun to do...experimenting with different woods, different shapes, and different sizes would definitely open up to many possible voice outcomes...I haven't seen many people experimenting with the bridge yet...have you?...I might have to set up few (sanding and cutting) machines for that purpose...not during our dead-cold Canadian winter...maybe next spring! :):D

Are you serious?

Well, I can, if you freely admit that you made up the idea of reverse bowing to fool an entire Erhu world. :D:D:D (unevenly distributed ions... HUH! Some idea!!!)

Seriously speaking, I do not feel like hand sculpting again, only if I can get a nice piece of African ebony, cos that is the one I want to try next. But since you are such a nice, helpful fella, I can sand you a boxwood one the next time I start using my Dremel, if you are serious.

Sidetrack: Yesterday I took the kid to the circus for the first time. It was the Chinese National Circus touring here. I love those girls and guys and what they do. I had anticipated some Erhu music there, but there was not any. Seems they had not brought a musical band with them. A local violinist was having his big time trying to imitate Erhu on a violin. His violin was sent through an effect box to make is sound more nasal. It rather sounded like a Gaohu than like an Erhu, though. He played everything from scores and tried his best, but an Erhu is an Erhu, and a violin can not fool my soul long. Anyway, this whole bullshit was about to introduce the picture of the loveliest gal of the show. She had a smile that shone through the rest. Here she is. Don't say I am not the sharing type...

That's a million dollar (USD) smile :D:)

Very time consuming to hand-sculpt hard wood...I once tried to hand-sculpt a bowl in exchange for an aged redwood post (more than 16 inches in diameter and 5 feet in length)...torn down from an old building!...it took me 2 weeks to finish the shape...of course I didn't work 24 hours a day...but at least a good 20 hours in total...I gave it to the guy without finishing the bowl...I really didn't want to spend my entire X'mas on the bowl!:2dead::D:)

Haha....But seriously, I'm serious about you sending the bridge to me.  I can pay you the shipping fee and any materials fee involved. I thank you in advance.

Regarding the reverse bowing, no I didn't make that up. I'm not sure if the Erhu maker made it up, but it sure is fun to do!  Not to the people around you though.

OK. No problemo. Next time I sit down to sculpt, I'll make one for you. Let me know your height preference and if you want it with slots, or you'd rather slot it for yourself. Also, circular or oval.

I tried reverse bowing yesterday for a short time (I am afraid to break some lines of the horsehair) and asked the neighbor if he liked it. He plays the accordeon, and somehow he is able to play it totally out of tune (how can one do that with a keyboard instrument???), so no one should dare to pity him...

Cheers,

B.

FOR FURTHER CONSIDERATION: Two strange ideas (not mine)...

No. 1. is only an unorthodox-looking bridge.

No. 2. looks much more dangerous. Look at the long piece in the middle. I bet it is not a stress releiver dovel stick, but rather a long bridge that vibrates the edge of the resonator box as well. Look at the bone insert at the middle. I bet that is where the strings sit.

Needless to say: Both of these ideas are JAPANESE. (Just as Karaoke is... :talk:)

More to come...

Bayun, I'm impressed with your web searching skills. You managed to find such interesting stuff. I'm begining to wonder if you know Chinese and Japanese.

The long thing with the bone in the middle doesn't look like it can fit the Erhu.  You sure its for the Erhu?

Yes I would like the bridge with slots and round.

By the way, I have another Erhu customer called Benedek who lives in Hungary, Budapest. I didn't know Erhu is so popular in Hungary (although 2 in the whole of Hungary doesn't count as much) Or you two happen to be the same person?

Sung Wah,

Hungary is not that big. Only has room for one Erhu-nuts. Some Chinese living here might be playing, but I have never met one. There are a lot of Chinese stores around here, but whenever I inquire about Erhus, they give me the look.

Ahm the same person with split personalities, like Dr. Jekyll and Hyde. I thought you had figured that long ago... :D Bayun is plainly Ben in the southern US accent. A Georgian friend addresses me that way.

Not a plain word in those languages. Ahm trynna be inventive. I paste Chinese characters from Answers.com of the topic I want to search. There are a lot of stuff up there that is not pinyinized. I will post some fun pics about fitting the snake skin, or on what crazy Qian Jins there are on the market. You might already have bumped into most of them... I am curious as to what those experienced fellas like you and Clyde can comment on such pics.

So what height do you want for that bridge?

B.

BTW, that stick-type bridge might belong to the double-boxed Erhu in the freak show thread. That is only a guess. It might be topped on the two plain bridges. But it might as well be just about anything else... . I only supply the pics and some layman's theories, the explanations oughtta come from someone more experienced...

Ah....So its you Ben. I'll let you know the height fo the bridge later.

Bridge No.1 looks alright actually.  I imagine it will give a brighter and not so nasal tone.

The stick type bridge I really have no idea how it fits in.  Its more believable if you tell me its an Erhu peg instead.

Boxwood project, bridge No. 2.

This one I sculpted after the pricey jewellery-case bridges of the Tianjin Wang Nai Zheng company showed in another thread. Sculpting the bridge and polishing off all the edges to a smooth-line finish took me two hours. I think this kind of work is what you have to buy for 50 bucks when buying those showcase bridges. You cannot reach that smooth appearance without hand labor.

The mass of this one is slightly bigger than the last one. It is round and the base circumference is bigger. I haven't glued cloth under this one, yet is sounds similar to the previous one that is smaller but has the cloth underneath.

After the second bridge I still hold my opinion. Boxwood is a better material than what those low-priced white wood and black wood factory bridges are made of. It supplies an enhanced mid-range, less dark-colored lower notes and a less nasal upper register. As for the smoothed shape, I think this bridge gives a louder tone and a good balance, but the difference compared to the previous one is marginal.

wowee, you're giving them a run for their money.

By the way, the bridges are sold exclusively through WNZ company.  The maker of the bridge is actually PSG.

There is a type of pencil bridge, where you cut a piece of pencil and dig out the lead in centre to obtain a tube.  I think Chen Yao Xing, the one who wrote, Zhan Ma Ben Teng (galloping of war horses) uses this kind of bridge.

Talking of pencil, I found a pic of another VERY INTERESTING bridge that is marketed. Now, this I would really like to hear in action. It must make some real difference. The company that sells it also sells conventional bridges.

It loooks concave in the middle, so it touches the skin only off the center and at the edges. No skin sagging in the center, and tone must be a great deal mellower. The bridge mass is gigantic as well. Must also mute the volume some. I may try this one day...
